摘　　要：复杂地形约束下的城市空间拓展面临一系列棘手且迫切的现实问题,但针对该领域的相关研究成果尚不充分,探讨优化此类城市的空间结构以突破发展困境,尤为重要。鉴于此,试图建立起一个以矛盾范畴为核心的研究框架。首先,抽象地形制约下城市空间结构面临的主要矛盾,包括自然本底、开发建设、出行系统、区域水平和地域特色五个方面;其次,提出"融合+适应+协同"思维的有效解决形式,挖掘出供给与需求关系是矛盾化解的根本所在;最后,进一步从供给侧、需求侧和供需侧三方面探讨空间结构具体优化路径,涉及资源重组下的可持续供给,规模、用地和交通层面下的生态化拓展,多尺度边界修正下的供需平衡。Urban space expansion under complex terrain constraints faces a series of difficult and urgent real problems,however,relevant research results in this field are still insufficient.It is particularly important to explore the optimization of the spatial structure of such cities to break through the development dilemma.In view of this,the article attempts to establish a research framework centered on contradictory categories.First of all,the main contradictions faced by urban spatial structure under the abstract terrain constraints include five aspects:natural background,development and construction,travel system,regional level and regional characteristics.Secondly,it puts forward the effective solution form of"fusion+adaptation+synergy"thinking,and finds out the relationship between supply and demand is the root of contradictory solution.Finally,the paper further explores the specific optimization path of spatial structure from the supply side,the demand side and the supply and demand side.It involves sustainable supply under resource reorganization,ecological expansion under scale,land use and transportation level,and supply and demand balance under multi-scale boundary correction.
